Instagram is a mobile-only photo-sharing app. It grew from 1 million users in January 2011 to 15 million in December 2011. It has 30 million users now.

What's great about it is that it is very fast – especially compared to Facebook.

With the Facebook iPhone app, there are 6 screens a user has to go through before a user can actually take a picture. With Instagram, there is one.

Facebook has acquired photo-sharing app Instagram for approximately $1 billion in a combination of cash and shares of Facebook.

Facebook CEO Mark Zuckerberg announced the acquisition in post on his Facebook Timeline Monday. The sale is expected to close later this quarter, and will bring the staff of Instagram to the social network.

“For years, we’ve focused on building the best experience for sharing photos with your friends and family,” Zuckerberg said in the post. “Now, we’ll be able to work even more closely with the Instagram team to also offer the best experiences for sharing beautiful mobile photos with people based on your interests.”

Zuckerberg went on to say that the company will be building on Instagram’s strengths and features and growing the app independently rather than “just trying to integrate everything into Facebook.”

Facebook plans on keeping features within the app that allow photos to be published on other social networks, and the ability to have followers and follow people who are not necessarily your Facebook friends. “We will try to learn from Instagram’s experience to build similar features into our other products. At the same time, we will try to help Instagram continue to grow by using Facebook’s strong engineering team and infrastructure,” Zuckerberg said.

This is the first time Facebook has acquired a company or product with so many users. “We don’t plan on doing many more of these, if any at all.” Zuckerberg said. “But providing the best photo sharing experience is one reason why so many people love Facebook and we knew it would be worth bringing these two companies together.”
